First of all, pay attention to the rules of three meals, eat seven or eight points full, and don't eat before going to bed at night. Avoid hard, greasy and spicy food, and keep warm. Stomach disease is a chronic disease, which can't be cured in a short time. The best way to cure a disease is to rely on "nurturing". If you can't hurry, you should first start with the change of living habits. We all need a good stomach, so it is necessary to change these habits.
A toast to your health.
